The Role of Commodities in Portfolio Diversification: 2025 Trends, Challenges, and Opportunities
April 29, 2025
Portfolio diversification remains a crucial strategy for managing risk and optimizing returns. Traditionally, diversification centered around stocks and bonds. However, as economic uncertainties mount, commodities, from gold and oil to agricultural products and industrial metals, have re-emerged as powerful tools for enhancing portfolio resilience.
Offering inflation protection, low correlations with traditional asset classes, and the potential for superior performance during volatile markets, commodities have solidified their role as essential components in modern investment portfolios. As we navigate into 2025, their relevance is only growing.
Why Commodities Matter in Portfolio Diversification
- Low Correlation with Traditional Asset Classes
One of the primary reasons commodities are valued in portfolio construction is their historically low, and at times negative, correlation with equities and bonds. When equity markets plummet, commodities often either remain stable or rise. For example, during the 2008 global financial crisis, while the S&P 500 dropped 38%, gold prices surged over 5% as investors sought safe-haven assets.
Hedge fund managers highlight that integrating commodities into a traditional portfolio significantly reduces overall volatility while improving risk-adjusted returns. Particularly in times of market stress, commodities can act as essential stabilizers.
- Natural Hedge Against Inflation
Commodities are often seen as a frontline defense against inflation. Unlike stocks and bonds, commodities are tangible goods — oil, wheat, copper — that often rise in price during inflationary periods.
According to the World Bank’s Commodity Outlook 20241, energy, metals, and agricultural commodities tend to perform strongly during inflationary spikes, offering critical protection for portfolios when purchasing power erodes.
- Enhancing Performance During Market Volatility
During periods of high volatility, different commodities behave differently. Gold and silver shine during market downturns, while industrial metals and energy commodities tend to thrive during recoveries. The CFA Institute notes that including commodities in a diversified portfolio can “increase the probability of achieving higher returns with lower volatility,2 especially during periods of heightened market swings.

The start of 2025 has certainly been fraught, and at this stage, it appears unlikely that the coming quarters will be any less volatile. Commodities were the top performer over the quarter, boosted by a 19% rise in gold prices.
2025 Commodity Outlook: Key Trends
Sticky Inflation
After the inflationary shock of 2022, expectations for a quick return to 2% inflation have been dashed. As of late 2024, core U.S. inflation remains stubbornly above 3%. Factors such as the widening U.S. fiscal deficit, trade tariffs under the Trump administration, and tightening labor markets are fueling expectations for sustained inflation into 2025.
Historically, commodities have outperformed in high-inflation environments. The Bloomberg Commodity Index has posted annualized returns of +15% when inflation exceeds 2%, compared to just +5% when inflation stays below that threshold. Higher inflation supports stronger performance for commodities across sectors, making them even more critical in diversified portfolios.
U.S. Dollar Movements
Commodities are priced globally in U.S. dollars. A stronger dollar tends to suppress commodity prices, while a weaker dollar lifts them. Since late 2024, the Bloomberg Dollar Index has risen about 8%, driven by higher U.S. interest rates and expectations of new tariffs.
However, as economic pressures mount and global growth slows, many analysts predict headwinds for the dollar. A weakening dollar in 2025 would likely be a boon for commodities, particularly oil, gold, and industrial metals, and remove a major headwind for commodity performance.
Physical Market Tightness
While futures markets show slight Contango4, when adjusted for rising interest rates, many commodity markets, particularly energy and metals, remain in Backwardation, indicating tight physical supply.
Contango describes an upward sloping curve where the prices for future delivery are higher than the spot price (e.g., the price of gold delivered in 1 year is $1,400/oz and the spot price is $1,200/oz). Contango is common in the gold industry, where the commodity is non-perishable and there are storage costs. Contango exists for multiple reasons, including inflation, carry costs (storage and insurance), and expectations that real prices will be higher in the future.
Backwardation describes a downward sloping curve where the prices for future delivery are lower than the spot price. Backwardation exists for various reasons, including short-term events that can cause the spot price to rise above future prices. For example, if a major drought causes wheat crops to suffer, then the spot price may spike up above the future prices when growing conditions are expected to be normal again.
Tight inventories mean that even modest demand increases could drive substantial price spikes. Sectors such as copper (critical for electric vehicles and renewable energy), and agricultural commodities remain particularly vulnerable to supply shocks. Scarce inventories enhance the upside potential for commodities as demand rebounds.
The Impact of Trump-era Tariffs on Commodity Markets
The return of President Trump’s aggressive tariff policies, particularly targeting China, has reignited global trade tensions. During Trump’s first term, tariffs disrupted supply chains and reshaped commodity markets:
- Agriculture: Soybean exports to China fell sharply, devastating U.S. farmers.
- Metals: Steel and aluminum tariffs spurred price spikes, then volatility, as global supply chains adjusted.
- Energy: Oil prices were impacted by broader demand uncertainty linked to slower global trade.
Heading into 2025, a potential second wave of tariffs could further disrupt commodity markets, impacting prices in unpredictable ways.
Investing in Commodities: Strategies
- Commodity ETFs: Offers exposure without the complexities of futures markets (e.g., SPDR Gold Shares, Invesco DB Commodity Index).
- Direct Futures: For sophisticated investors comfortable with margin requirements and volatility.
- Mining & Energy Stocks: Provides indirect exposure (e.g., Freeport-McMoRan for copper, ExxonMobil for oil).
- Physical Commodities: Buying physical gold, silver, or energy assets.
- Volatility: Commodities are notoriously volatile; sharp price swings are common.
- Regulatory Risks: Environmental regulations, tariffs, and trade policies can alter supply-demand dynamics overnight.
- Storage and Costs: Holding physical commodities involves logistical and insurance challenges.
In today’s uncertain economic climate, marked by inflationary pressures, political instability, and supply chain vulnerabilities, commodities are no longer just an optional asset class. They are a strategic necessity for investors aiming to build resilient, future-proof portfolios. By providing inflation hedging, low correlations, and upside potential during global disruptions, commodities offer unique diversification benefits. As we move through 2025, astute investors will recognize that a well-balanced portfolio is not just diversified across stocks and bonds, but across fundamentally different asset classes — including commodities.5
